At least 11 protesters died as crowds angered by the killing of a prominent militant clashed with armed police in India-held Kashmir on Saturday, torching buildings and blocking streets, security officials has said.

Police sources said that demonstrators set fire to three police stations and two government buildings in towns south of Srinagar, and three officers had gone missing in the violence, Indian media reported.

Top Kashmiri leader Mir­waiz Umar Farooq accused police of using excessive force and questioned their version of events.

The protests erupted a day after security services shot dead Burhan Wani, a 22-year-old militant known for his calls to arms on social media. He led Hizbul Mujahideen, prominent among the groups fighting Indian control of the disputed Himalayan region.
